Abstract

A prediction block generating device of the present invention determines additional information for generating a prediction block included in an additional information container received, and an intra-prediction mode of a present prediction unit using valid intra-prediction mode candidate information of the present prediction unit; generates reference pixels that are not in a usable location for generating intra-prediction blocks by using usable reference pixels; adaptively filters the reference pixels close to the present prediction unit on the basis of the determined intra-prediction mode of the present prediction unit or size information of the present prediction unit; and generates prediction blocks of the present prediction unit using the reference pixels that respond to the determined intra-prediction mode of the present prediction unit. Therefore, the present invention can enhance image compressibility by generating prediction blocks close to the original image.
